"A month ago we looked at the Radeon HD 6550D graphics
performance from the AMD Fusion A8-3850 (a new "Llano" APU) under Linux
when using the Catalyst driver. However, bugs at the time had barred a
comparison of the Llano graphics under Linux with the open-source
Mesa/Gallium3D driver. Fortunately, we now have a working open-source
Radeon driver configuration to deliver these comparative AMD Llano Linux
OpenGL benchmarks."
